Can i run GTX 580 (slighty Oc ) in a corsair VX 550 watt PSU ??

post #1 of 7
Thread Starter 
Recently I bought a new Gigabyte GTX 580 which is factory overclocked to replace my old 5870 . My rig is core i7 870 ( 4.00GHz OC ) , 8 Gig ram, 2 HDD , 1 optical Drive and 7 fans. I never encounter any power related issue so far with my Corsair 550 watt. But now i can see in nvidias site that to smoothly run GTX 580 , i need a minimum of 600W PSU !! I was wondering if i can run this card with my current PSU , that is corsair vx 550 watt ( (+12v @ 41amp) without any trouble ? Please im in a tight budget so i really can use some helpful information . Many sites tell that A gtx 580 can be ran on machine with 550 watt. Hence im confused whether i should buy a new PSU or can keep using my corsair vx 550 ??

thankz thats a relief but just out of curiosity , i calculate my power requirement in Powercalc and it says something avobe 600 watt always !!! will you please take the effort and tell me if i still can overclock my cpu to 4.00 ghz ( 1.37 v ) and still can use my GTX 580 ( stock 772 but it is 800 mhz ) with my VX 550 watt ?

Tests showed that the full system power consumption with a GTX 580 is somewhere between 400-500W. So you should be fine. But CPU and GPU overclocking can drive up the power consumption quite a bit.

According to Phaedrus' PSU Calculator, you will need at least 575W.

I would suggest getting a good quality 650W psu. I have a Corsair TX650 v2 and has been a beast this past year since I got it.

Don't worry anymore.
